In modern operating systems, applications do not directly access the physical memory. Instead, they use so-called virtual memory, where each virtual address is translated to a phys
How a virtual memory can be implemented? What are the benefits of using virtual memory?
Assume that P A , P B and P C are three distinguished program s . When P A is executed, it needs 10 ticks to complete its execution and it forks new processes executing P B at tick
Deadlocks can be detected while the program is running, by running cycle detection algorithms on the graph that de?nes the current use of resources. De?ne this graph as follows:
Problem: a) Define a ‘file' and list the objectives of the file management system. b) List the ways in which programs access files and determine for what file types you woul
